Nextgel Polymeric Sand Calculator For Pavers

Polymeric Sand Formula:

\[ \text{Sand (lb)} = \text{Area (ft²)} \times \left(\frac{\text{Joint width (in)} \times \text{Joint depth (in)}}{144}\right) \times 100 \]

1. What is the Polymeric Sand Formula?

The polymeric sand formula calculates the amount of Nextgel sand needed for paver joints based on the area of the project and the dimensions of the joints between pavers.

2. How Does the Calculator Work?

The calculator uses the polymeric sand formula:

\[ \text{Sand (lb)} = \text{Area (ft²)} \times \left(\frac{\text{Joint width (in)} \times \text{Joint depth (in)}}{144}\right) \times 100 \]

Where:

\( \text{Area} \) — Total area of the paved surface in square feet
\( \text{Joint width} \) — Width between pavers in inches
\( \text{Joint depth} \) — Depth of the joints in inches
144 — Conversion factor (square inches to square feet)
100 — Density of polymeric sand (lb/ft³)

Explanation: The formula calculates the volume of joints in cubic feet and multiplies by the density of the sand to get the weight required.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase the right amount of polymeric sand, avoiding waste or shortage during installation.

4. Using the Calculator

Tips: Measure your project area accurately and determine the average joint width and depth. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is joint depth important in the calculation?
A: Deeper joints require more sand to fill them completely for proper stabilization and weed prevention.

Q2: What if my joints vary in width?
A: Use the average width for your calculation or calculate different areas separately if widths vary significantly.

Q3: How much extra sand should I purchase?
A: It's recommended to buy 10-15% more than calculated to account for settling and waste during installation.

Q4: Does this calculation work for all types of polymeric sand?
A: The formula works for standard polymeric sands with similar density. Check manufacturer specifications for specialty products.

Q5: Can I use this for irregularly shaped areas?
A: Yes, as long as you can calculate or estimate the total square footage accurately.
